Are the measurements expressed in millimeters, centimeters, or inches? What does 0.02 under size mean? Are that 0.02 inches? or centimeters?

Willys Jeep Parts Tech:
Those are all in inches.

In what measures are the pistons expressed? what does o.s mean? In the case of the main and rod bearing, what does u.s mean? Thanks for your reply.

Willys Jeep Parts Tech:
When purchasing this kit, you have to get your pistons, main bearings and rod bearing sizes to ordered properly. The pistons will either be standard or oversized by the measurement you would take of the cylinders. The mains and rods would be standard or undersized based off the sizes of your crank shaft that you would have measured.

I have a 1960 Jeep CJ. I have yet to work on the engine. Does this engine have a timing chain? If so what part number.

The 4-cylinder, f head motor is gear to gear and does not have a timing chain. Thanks

i bought a 1966 cj5 with a 134 hurricane in it . had an engine knock. have completely disassembled . all standard very low miles. the only thing i have found is someone installed 2 pistons backwards on the rods & therefor the pistons were installed in the engine backwards. woud this cause a knock I was a heavy equipment mechanic fo almost 50 years , thought i had say everything

Willys Jeep Parts Tech:
It could if the cylinder wall was not getting oil correctly due to the rings being mis-installed. You would have to inspect to see what all is going on.

Can fit for willys M151 engine

Willys Jeep Parts Tech:
Yes, as long as you have the 4-134 F engine.

I don't know the mileage or history on the 4-134F engine in my M38-A1. Can you recommend whether I order a kit with standard components or oversized? If oversized, which oversize?

Willys Jeep Parts Tech:
You should have a machine shop inspect and see what size pistons and bearings you need. We have pretty much any size available.

Can I get the kit without the rod or main bearings? I already have them.

Willys Jeep Parts Tech:
You sure can. Just give us a call at 888-6484923 or email me at so we can work that up for you. Thanks
